Debt securities includes corporate bonds with fair value that is determined by third party quotations from outside pricing services and/or computerized pricing models, which may be based on transactions, bids or estimates. Acacia classifies the fair value of corporate bonds within Level 2 of the valuation hierarchy. Trading securities - equity. Equity securities includes investments in public companies common stock and are recorded at fair value based on the quoted market price of each share on the valuation date. The fair value of these securities are within Level 1 of the valuation hierarchy. Investments at fair value - common stock. Acacia’s equity investment in Veritone common stock is recorded at fair value based on the quoted market price of Veritone’s common stock on the applicable valuation date. The fair value at December 31, 2017 was adjusted for an estimated discount for lack of marketability (“DLOM”) associated with the restricted nature of the common shares under a lock-up agreement at December 31, 2017 (Level 3 input). At December 31, 2018, there were no restrictions on the common shares and the investment in common shares was transfered from Level 3 to Level 1. Investments at fair value - warrants. Warrants are recorded at fair value, as based on the Black-Scholes option-pricing model (Level 2). Warrants on securities under a lock-up agreement are adjusted for an estimated discount for lack of marketability (“DLOM”) associated with the restricted nature of the common shares (Level 3). Profits interests. For the year ended December 31, 2018, the fair value of the Units was estimated at 40% of the fair value of the 10% Warrant, based on the Black-Scholes option-pricing model (Level 2). For the year ended December 31, 2017, the fair value of the Units was estimated based on probable vesting dates and values for the applicable instruments (i.e. common stock and warrants related to Acacia’s Veritone investment described at Note 6) underlying or associated with the Units (Level 3).
